Answer:
CB = 5, 
Step-by-step explanation:
Assuming that the marks next to angle D mean that 
, then there is enough information to conclude that the two right triangles are congruent (HA theorem--hypotenuse/angle).
Then all the corresponding parts of the two triangles are congruent, including segments BA and BC, making them the same length.
4x + 1 = 9x - 4
Solving for x,
1 = 5x - 4
5 = 5x
1 = x
Pluggint x = 1 into the two expressions reveals that the length of segment CB is 5.
The two small angles at D are congruent, so 
.
Answer:
Step-by-step explanation:
Given
x - 2 - 2x
= - x - 2
Answer:
$27 per week.
Step-by-step explanation:
Multiply:
$2.65 x 8 (twice per day)= $21.20
$1.45 x 4 (once oer day)=$5.80
Add those together to get $27 per week.
Answer:
40
Step-by-step explanation:
Step-by-step explanation:
Sure, that's easy. Although the equation isn't clear to me with characters. I can't seem to figure out whether the x is a multiplication symbol or the variable x. Would you mind writing it on paper and uploading a picture? Then I can help
